I was trying to teach some pupils how to display the formulae rather than the
answers. The method involves changing a setting in Tools Options.

As often the case, I try to encourage the use of the help system ... but I
could not find this in the help file using any common keywords that I could
think of. Is it there? What keywords should I be using.

All I kept coming up with is hide/unhide for protected cells.

Many thanks

Martin.
